With the squeaking of the drivers seat i believe their is a fix discussed before here at ozhonda search 'squeaky seat' i think by memory you might have to pull the whole lumbar section out didn't actually do it myself but am going to later as i never use it.
....This should be covered under warranty as well upto you if you want to pursue it under warranty or get them to take out the lumbar bit for you.
Hope this helps....
